The investigation of interactions between the abilities of stimulus discrimination and simple learning and two instructional variables (discrimination difficulty and degree of overlearning) with 27 mentally retarded adolescents found an interaction between stimulus discrimination and the number of words presented at one time for learning…

The report presents summaries of 11 studies performed on 25-45 autistic students in a residential center to investigate processes of discrimination and response acquisition using automated reinforcement technology and exact timing procedures. The computer operated display and recording system for language and discrimination training is described…

Three experiments examined the perception of a three-way voicing contrast by monolingual speakers of English. The results demonstrate that the perceptual mechanisms used by adults in categorizing stop consonants can be modified easily with simple laboratory techniques in a short period of time. (Author/PN)

This study examined the relationship between discrimination error (determined by content analysis and tryout data) and confidence of response (determined by self report). Subjects were 63 undergraduate students enrolled in a biology class for nonmajors who received classroom expository information and read a text on the topic before they completed…

This report describes a computer drill called the Corrective Feedback Paradigm (CFP) and summarizes a research study which examines the effects of the CFP on posttest and time to mastery achievement. The CFP, which embodies the use of such principles as mastery learning, increasing ratio review, and discrimination training, is capable of being…

Describes a study in which preschool children, enrolled in a Head Start Program in Texas, tested computer-assisted instruction facilitating visual discrimination. The study, in which a TRS-80 Model III displayed alphabetical characters, showed that four-year-olds are able to learn simple visual discrimination tasks from a computer. (JJD)

The effects of four methods of immediate corrective feedback delivered by computer within a question-based concept and rule learning setting were investigated in this study. A second purpose of the study was to probe the complex relationship between types of corrective feedback and the types of errors made by learners. One hundred and fifty-three…

In two studies with 50 male and 50 female undergraduates, differences in learning highly interfering paired-associate discrimination tasks were compared with or without visual mediational cues and with aural cues only. Visual mediational instruction reduced interference between similar signals and facilitated their association with the correct…

Describes the theoretical backgrounds and empirical findings of three experimental studies in which computer-based response-sensitive strategies were investigated using concept learning tasks. The strategy applied focused on discrimination learning, generalization learning, and classification skill development in concept learning. A general…

This study evaluated the effectiveness of a multimedia computer-based instructional program with four middle school students with moderate/severe mental retardation in establishing match-to-sample skills and generalizing those skills to the natural setting (a grocery store). In vivo probes found mean and median duration to find target items…

This report summarizes the results of research studies on instructional practices that significantly affect the cognitive, language, or mental abilities of students with disabilities. The investigation reviewed current research on instruction of students with moderate disabilities and sought to identify effective instructional practices. The steps…
